PRODUCT INTRODUCTION
description
Tristearoylglycerol is a triglyceride that is glycerol in which all three hydroxy groups have been formally esterified with stearic acid. It has a role as a plant metabolite and a Caenorhabditis elegans metabolite. It is functionally related to an octadecanoic acid.
